压缩通过C#套接字发送的数据?

[英]Compress the data sent via a C# socket?

I'm trying C# sockets to send images. 我正在尝试使用C#套接字发送图像。 It works, but it's unstable. 它可以工作,但是不稳定。 The images sent through are quite large and are updated very quickly which causes it to flicker every now and then. 发送的图像很大,并且更新非常快,这使其不时闪烁。 I'm looking for a way to compress the data sent if possible. 我正在寻找一种方法来压缩发送的数据(如果可能)。 I'm using this code: 我正在使用此代码:

Server side: 服务器端:

System.IO.MemoryStream stream = new System.IO.MemoryStream();

// !! Code here that captures the screen !!

bitmap.Save(stream, myImageCodecInfo, myEncoderParameters);

byte[] imageBytes = stream.ToArray();
stream.Dispose();

// Send the image
clientSocket.Send(imageBytes);

// Empty the byte array?
for (int i = 0; i < imageBytes.Length; i++)
{
    imageBytes[i] = 0;
}

Client side: 客户端:

private void OnConnect(IAsyncResult ar)
{
    try
    {
        MessageBox.Show("Connected");

        //Start listening to the data asynchronously
        clientSocket.BeginReceive(byteData,
                                    0,
                                    byteData.Length,
                                    SocketFlags.None,
                                    new AsyncCallback(OnReceive),
                                    null);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Stream Error",MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

private void OnReceive(IAsyncResult ar)
{
    try
    {
        int byteCount = clientSocket.EndReceive(ar);

        // Display the image on the pictureBox
        MemoryStream ms = new MemoryStream(byteData);
        pictureBox1.Image = Image.FromStream(ms);
        }
    catch (ArgumentException e)
    {
        //MessageBox.Show(e.Message);
    }
    clientSocket.BeginReceive(byteData,0,byteData.Length,SocketFlags.None,new AsyncCallback(OnReceive),null);
}

I ended up using gzip. 我最终使用了gzip。

Turns out the flicker wasn't due to it being updated very quickly, but was because of the way I had sockets set up. 原来,闪烁不是因为更新非常快,而是因为我设置了套接字。 It wasn't sending the whole image. 它没有发送整个图像。
